Abstract
A method, apparatus and computer program product enhance audio quality during a voice communication session, such as by enhancing audio quality for a remote participant in a meeting. In a method and for each of two or more microphones of a first device at a first location, a target audio signal is generated that has been steered in a direction of a target audio source in order to provide at least partial isolation from a second audio source in the same environment. The method also produces a filtered audio signal based on the target audio source at least from a respective one of the two or more microphones. The method also includes mixing the filtered audio signal from at least the first device to create an audio output signal associated with an audio playback format and causing the audio output signal to be output by a second device.
